My grandfather was an old Russian whose views on dealing with USSR boiled down to détante, or in his immortal words, "once they have a pot to piss in, they won't fight..."
The flipside to that is, China does now have a pot to piss in, and is far less likely to be kettled into a war over something as stupid as an overabundance of crappy housing.
Does this mean "once the people have a normal life, they won't want a war?"
I am seeing the opposite. All dictatorships seem to start getting land conquest ideas once they have the resources. There is a direct correlation between Russia's cash reserves and their belligerence, for example. China is becoming one man, just like Russia is Putin, and it's also becoming a less rational actor as the result.
Allowing the housing bubble (which seems to have enriched those close to the party), punishing the tech sector for their own success, the completely baffling Zero Covid. At some point it's the dear leader's ego and quest for "legacy", not the economy.
